3.5 Mechanical Characteristics

3.5.1 Mechanical Strength

An AC Servomotor can withstand instantaneous peak torque on the output shaft of up to 300%
of the motor rating.

3.5.2 Allowable Radial and Thrust Load

The output shaft allowable loads of AC Servomotors are shown below.
Use mechanical designs where thrust and radial loads do not exceed the values below during mo-
tor operation.
